I am using a real estate commercial theme, that uses a custom login/registration from on the frontend.
The admin panel and option pages are restricted to Administrators, but if the theme is deactivated, non-Admins can visit the admin panel and see the setup options for listing authors.
When the theme is active, Authors only see the front end of the site with the front end login.
I have embedded an iframe using another popular WP plugin into the User Front End form.
In the IFrame the WP login can be accessed that would lead to the core WP Admin screen where the plugin is seen and is available for Users with Author roles.
But I need for this WP Admin view to open with the same Username and Password as the Front End.
What is the best way of passing the User's Front End login credentials back to the core WP Admin inside the IFrame?
So that when the IFrame calls up
wp-admin/plugins.php that it will display the same core
wp-admin view as if the real estate theme had not been installed?
Neither the custom real estate developer nor the IFrame plugin developer have an answer for this situation.
